The Mazda 5 has a 2.0L displacement, with all models equipped with a 2.0L naturally aspirated engine. It is currently out of production. Below is an introduction to displacement: Displacement is one of the important parameters of an engine: The volume of space that a piston moves from the top dead center to the bottom dead center is called the cylinder displacement. If the engine has multiple cylinders, the sum of the working volumes of all cylinders is called the engine displacement, usually expressed in liters (L). Engine displacement is one of the most important structural parameters, more representative of engine size than bore and cylinder count. Many engine metrics are closely related to displacement. Displacement classification: In China, passenger car classifications are determined by displacement. Mini cars have a displacement of ≤1.0L, compact cars range from 1.0-1.6L, midsize cars range from 1.6-2.5L, executive cars range from 2.5-4.0L, and luxury cars have a displacement >4.0L.

The Mazda5 is equipped with a 2.0L engine across all trims. I've driven this car for six years, and it's particularly handy for city commuting—never feeling underpowered, and the fuel consumption isn't excessive either. Last time I went to the used car market to help a friend pick a car, I noticed that this engine is robust and durable, with affordable maintenance costs. However, the older naturally aspirated engine indeed lacks the explosive power compared to today's newer turbocharged models, but it's more than sufficient for family use, carrying a full load of people, or going on trips. The matching between the engine and transmission is exceptionally smart.

My best friend's blue Mazda5 is a 2012 model, equipped with a 2.0L inline-four engine. It's perfect for picking up and dropping off kids at school, and taking parents to the supermarket on weekends. The fuel cap indicates that 92-octane gasoline is sufficient. Last year, when I rode in her car on the highway with four people and luggage, the acceleration for overtaking was quite smooth, but I remember the dashboard showed an average fuel consumption of about 8.2 liters per 100 kilometers.

The Mazda 5, produced from 2005 to 2018, consistently utilized the MZR series 2.0-liter engine across all model years. It's quite interesting to see a maximum output of 144 horsepower applied to a tall-bodied MPV, especially when paired with the 5-speed automatic transmission that delivers a uniquely smooth shifting sensation. I've studied its dual overhead camshaft design, which demonstrated better valve control efficiency at low speeds compared to the contemporary Honda Odyssey 1.8L.
